LHJXQ Industrial-Grade Intelligent Adaptive Bidirectional RS485 Hub

Product Overview

The LHJXQ Adaptive Bidirectional RS485 Hub is a high-performance interface conversion device designed for industrial communication scenarios, functioning as both an RS485 splitter and distributor. Built with industrial-grade anti-interference chips, multi-layer surge/ESD protection, and smart data flow control, it eliminates latency and interference in traditional RS485 networks, delivering stable, efficient, and transparent data transmission for mission-critical environments.

Core Advantages

✅ Industrial-Grade Robustness
Equipped with 1,500W surge protection and 15kV ESD shielding, it withstands lightning strikes, electromagnetic interference, and electrostatic discharge, ensuring reliability in harsh conditions.

✅ Automatic Data Flow Control
Embedded intelligent recognition chip auto-detects data direction and switches transceiver circuits instantly, enabling zero-delay transparent communication without manual intervention.

✅ Multi-Port Isolation & Protection
Active isolation technology ensures electrical separation between ports. Even if one port is short-circuited or disconnected, others operate normally, eliminating cross-talk risks.

✅ Scalable Connectivity
Supports 4/8/16-port configurations (customizable), with each port connecting up to 256 devices. Cascading enables expansion to 256 enhanced RS485 nodes, ideal for large-scale networks.

✅ Extreme Environment Adaptability
Operates in -40°F to 185°F (-40°C~85°C) temperatures with 9-36V DC wide-voltage input, ideal for harsh industrial environments.

Key Features

· High-Speed Long-Distance Transmission: Up to 115.2Kbps speed with 1,200 meters extension per line pair, breaking RS485 distance barriers.

· Universal Protocol Support: Plug-and-play compatibility with MODBUS, PLC, access control, CCTV systems, and all RS485 protocols.

· Multi-Layer Safeguards: Short-circuit/break protection, lightning/ESD shielding, and isolated ports for network integrity.

· Real-Time Diagnostics: LED indicators for power/data status per channel, enabling quick fault detection.

· Industrial Durability: Flame-retardant housing with 35mm DIN-rail mounting, ideal for space-constrained installations.
